高度近视后发障Ⅱ期研磨术临床探讨

Clinical observation of posterior capsular polishing in the treatment of high myopia patients with posterior capsular opacification

目的研究高度近视白内障摘除或联合人工晶状体植入术后引起的Elschnig珍珠样小体型后发障的有效治疗方法。方法对42例47眼Elschnig型后发障进行后囊研磨术,术后随访10～48个月。结果术后矫正视力≥0.5占55.3%,影响术后视力主要原因为高度近视所致眼底病变。未发现瞳孔区玻璃体疝、黄斑囊样水肿或视网膜脱离等并发症。结论后囊研磨术是后囊混浊的有效治疗方法,适应证是Elschnig珍珠样小体型后发障,尤其对高度近视及无人工晶状体眼更为安全。

Purpose To study the effective treatment for the posterior capsular opacification in patients with high myopia and 'Hirschberg-Elschnig pearls'. Methods Posterior capsular polishing was performed on 42 cases (47 eyes). The patients had been followed up for 10 - 48 months. Results The rate of postoperative corrected visual acuity over 0.5 was 55.3 % . The main cause of the poor visual acuity is due to the pathologic changes of the fundus in high myopia. The complications of vitreous hernia, cystoid macular edema or retinal detachment have not appeared. Conclusion We think that posterior capsular polishing is an effective and safe therapeutic method for the treatment of posterior capsular opacifcation in patients with high myopia and 'Hirschberg-Elschnig pearls'.
